Oliver Schmidt d5092d2d3f Consider the segment attributes 'define' and 'optional' mutually exclusive. 
In normal situations it isn't too useful to define symbols for optional segments as those symbols can't be presumed to be always present.

I in fact suspect that most currently present combinations of 'define' and 'optional' aren't useful - apart form the overlay configurations of course.
